The issue is probably an encoding issue. We had something similar when our
server was serving up UTF-8 pages after we ran a patch update. Previously it
was using ISO-8859-1. The change caught us off-guard (though was good for
our purposes in the long run).
Not sure if it's an issue, but the character set on the page is listed as
UTF-8. If the Chinese characters were entered using a different encoding,
that could be an issue.
Just throwing this out there...
